alt Hacker NewsSee also, https://objectiveunclear.com/airloom.html?airport=MSP . Another very nice 3D viewer for adsb info.
Both this post's viewer and the older one I linked directly above have greatly exaggerated vertical scaling. It is not proportional to the distances on the map. With actual 1:1 height scale all these planes, even the stratospheric jets, would be much closer to the ground.
Currently it servers more aesthetically than accuracy when it comes to vertical scaling, its on the feature list to add 1:1 height scale, it isn't as pleasing to look at but definitely a must have.
